The Educational Technology Plan issued in 2021 by the Ministry of Education of Singapore is the fifth strategic plan in the history of educational informatization in Singapore.Based on the ecological view of educational technology,the plan is committed to cultivating"future-ready"digital learners.Its implementa-tion path includes providing personal mobile learning terminals,developing"personalized"learning platforms,enhancing the cultivation of students'digital creativity,and creating digital assessment models.Teachers'digital literacy,collaborative system of stakeholders and digital space security are important factors influencing its implementation.Compared with the previous four plans(1997-2020),this new plan exhibits the distinc-tive hallmarks of legacy:adhering to the"human-centered"value system;emphasizing on the connection with the previous plans;promoting the systematic coordination between multiple stakeholders,and reinforcing inter-projected synergy.The innovative features are manifested in the conceptual reform of educational technology from"instrumental theory"to"ecological theory",from a"closed cycle"to a"rolling update"by introducing the principle of"agile methodology",and integrating new content such as"artificial intelligence and personal-ized education"and"seamless learning".
